The easy way is to buy a triple overflow. Finish it up. Then there is triangle overflow. Aesthetically good is the overflow of the four corners, which looks a bit atmospheric. The specific size is two overflow plates, one is an overflow water level plate, and the general height is = fish tank water level -0.5-1cm. The fish tank has a water level of 50 and the height of the overflow plate is 49 cm. The other is an overflow plate with a fish comb. Of course you can't. Then the interval between the two boards should be controlled at about 1 cm. Water pump The water volume of the fish tank is about 250 liters. It is sufficient to choose a pump between five and ten times the amount of water, which is between 1250-2500. Which other virtual standards and which pipes are missing, this data does not affect your filtering at all. A good design is not affected by such a small flow loss. So you don't have to think about it at all. do not worry. Here, I will choose a 2500-flow pump and try to choose a low-wattage, the legendary energy-saving inverter pump. But if the price is too high, choose an ordinary water pump. This pump has a flow rate of more than 100 units and is no longer worth using. For 250 liters of water, follow the formula for heating 1 liter of water at 1W. Considering heat loss, a 300 watt heater is standard. But I would consider two 300 watts, one at 28 degrees and the other at 26 degrees. In order to prevent a heating failure, there is another time to ensure the water temperature of the fish tank. Of course, some people think it's expensive and the electricity bill is the same. light The light is good for tourists to watch, but it also has some effects. In this regard, there are diving lights that are easy to install and use. There are also t5t8 and other aquarium professional lights. But it must be equipped with a lamp holder. Extractor for Shanghai Oceanarium: Ordinary filtration, especially bottom filtration, has oxygenation function. The oxygen content of water is limited. So in this regard, I would not choose to waste this money. From a safety point of view, instead, choose a dual-head air conditioner and a DC air pump, which are the cheapest. Place one end in the aquarium fish tank and the other end under the biochemical filter material.
